Evan promised "ring signatures in V2"
Yesterday he had to back peddle and admit it couldn't be done on a Bitcoin fork. You can't trust this kind of behaviour.

Darksend is closed source, no one with half a brain would trust closed source software. I can't wait to see the math on a whitepaper.

If Evan ever comes up with something groundbreaking (will not happen) the Bitcoin devs can copy and implement it. On the other hand, they can never copy cryptonote based coins.
